I LOVE OTF - it makes my day when I go! I love how intense the workout is - but also that I can cater it to my own pace. I also love the scoreboard, as I find it very motivating to push myself harder.
I did want to provide some instructor feedback, however. I typically attend the 5:30am class on Wednesdays and to me Eric was the perfect instructor. He was incredibly motivating and provided amazing workouts - also a great personality that resonated with students. I am not feeling the same from Mikey unfortunately. I find myself watching the time more, as he doesn't engage as much throughout the class (there are a lot of silences whereas Eric was great at keeping the energy flowing all throughout class). It is also very difficult to understand him and it seems many are often confused about what they should be doing. Not sure what the temperature has been no him overall - quite honestly his presence is a bit lackluster compared to your other instructors. It seems you should be putting forth your top personalities for prime time classes.
Class size, every workout is different, motivating trainers who are all in shape and fit themselves, everyone who works out there is so nice and it's like a little family, I actually see results in my body.
